You MUST see the parade and you MUST see the fireworks. We tend to campout between the parade and the fireworks and watch them both from the Hub.
If you want to go trick-or-treating, just know that the candy is the same (for the most part) all around the park, so you don’t really need to hit every spot unless someone wants to. My favorite place to go is Alice & the Mad Hatter’s Trick or Treat Trail. Great decorations and lots of candy stops!
The Villains Mix & Mingle show is pretty good, but the best part is the actual mixing & mingling afterwards! However, there are like 6 villains all out at once and they leave pretty quickly. So definitely get in line for your favorite villain first. I got pictures with Facilier and Maleficent last year! We were in line for Jafar when the villains had to leave.
I like to focus on the party atmosphere rather than the attractions. Haunted Mansion is an absolute MUST DO for me (well, it is all the time, but especially MNSSHP, because there are some subtle changes for the party!) but besides that, we just do what we feel like and what has a short line.
My number one tip: don’t stress out! I know it’s hard not to when you’ve spent so much extra money on a 5 hour party, but that’s what you paid for - a party! So have fun! Enjoy the special things going on at the party (parade, fireworks, special characters, etc.) that day guests don’t get to see. Don’t get bogged down by how much there is to get done - enjoy the fact that there is so much going on and you get to be a part of it! :happy:
